The rounded corners of the WinForm form are not easy to set or draw. I searched the Internet for many solutions and finally found a perfect solution. Redraw the corners of the window is commonly used in online information. But in a different way and finally

In the last article, we created a Web server with basic static file service functionality, but without dynamic functionality. We hope to further expand this program into a fully functional dynamic Web server. But before you get too busy writing code, let's think about what a Web framework should look like at an architectural level. Although different programming languages are real...

The day before yesterday, a friend of wX threw me a dump, asking me to help verify whether some sensitive information is encrypted in the memory. Nowadays, data security is very important. Not only the information in the database should be encrypted, but the data after pouring into the memory should also be stored in ciphertext and decrypted at any time.

23333333. Let me laugh for a second. In three words, solve!!!! Decoupling!!!!!!!!!! Us!!!!!!!!!! . What takes a few lines of code is not so easy to implement. You can see that the receiver implements the interface IMsgReceiver and the sender implements the interface IMsgSender. So let's look at these two interface definitions. Nothing. There is no SendLogic...

Stay tuned for... Develop Activex controls for other applications to call, this chapter explains C# calls Activex controls, not limited to Qt developed Activex controls. To make Wpf calls to Activex controls, it is necessary to wrap the Activex controls in C# and provide them to Wpf calls. Register before running, use Qt's built-in...

In this article, the second in a series on C#, we will use.net Core, the C# cross-platform framework, as an example of how to write large back-end application projects in C#.

In the last article, we implemented the routing capabilities of the Web server and implemented basic support for the controller. We should have happily continued to add functionality to it, but soon discovered an embarrassing problem ———— we don't have a Session yet. More specifically, the HttpListenerContext we've been using only provides Req...

As I mentioned earlier, this is a process-level cache that can be seen by multiple threads, so in a multi-threaded environment, you need to pay special attention to synchronization. Either use lock or ConcurrentDictionary, I think this is also a mindset, a lot of times the mind is trying to fix the existing base...
